To all whom it may concern:

Be it known that'we, ARTHUR S. HYDE and CHARLES GORDON, citizens of theUnited States, residing at Hartford, in the county of Hartford and Stateof Connecticut, have invented a new and useful Improvement in a Coolerfor Automobiles, of which the following is a specification, accompaniedby drawings forming a part of the same, in whicha Figure l is aperspective view of an auto= mobilecooler, with a portion shown insectional View in order to disclose the construction of the radiatingsection of the cooler.

' rangement of Fig. 2 is an end View of two of the vertical sectionsinclosing the air spaces of the rad-iating section and the means forproviding a circulation of water through the radiating section. Fig. 3isa perspective view of the shallow pans which are inserted into theupper and lower ends of the sections through which the air circulates,for the purpose of closing the upper and lower ends of the air spaces inthe radiating section, and Fig. 4 represents a modified form of waterchannels.

Similar reference letters and figures-refer to similar parts in thedifferent views.

The object of our present invention is to provide an efliciei t andinexpensive construction for the c cling device employed in motorvehicles for cooling the water which has been heated by contact with thecylinders of an explosion engine.

The present embodiment of our invention comprises an upper water chamber1, a lower water chamber 2, and an intermediate radiating section 3through which the water passes from the upper to the lower chamber bygravity. A circulation is maintained between the lower and upper waterchambers by a pump or other suitable means similar to that now employedin devices of this class, and the circulatory water system comprises theengine cylinders by which the water becomes heated in its passage fromthe lower to the upper water chamber, and is cooled during its passagefrom the upper to the lower water chamber through the radiating sectionof the apparatus.

Our present invention refers particularly to the construction of theradiating section of a cooling apparatusof the class described, and itconsists in the construction and arparts as hereinafter described, thenovel features being pointed out in the annexed claims.

The radiating section embodying our invention comprises a series ofVertical sections, such as are shown in end View in Fig. 2 at 4, 4",each of the sections 4., 45" consisting of two strips of sheet metal 5and a 6' placed side by side and arranged preferably at right angles at7, forming three sides of a rectangular section and the flanges 8, 8,forming a part of the'fourth, The next adjacent section P is formed inthe same manner and placed in contact with theflanges 8, 8, completingthe fourth side of the section 4. One or both of the sheet metal strips,preferably the outer strip 6, is arranged at intervals to formsemi-circular grooves or channels 9 extending throughout the entirelength of thevertical sections, and constituting water channels throughwhich water may flow by gravity from the upper water chamber 1 into thelower water chamber 2. A sufficient number of sections 4:, P arearranged side by side to fill the space between the upper water chamber1 and the lower water chamber 2.

In the ends of each of the rectangular sections 4, 4* are insertedshallow sheet metal pans 10 having their sides shapedto lit the sides ofthe rectangular sections, one side being curved as shown at 11, 11, and12, 12, to fit the semi-circular water channels 9. Rectangular holes 13are cut at regular intervals through the front and rear sides lt of therectangular sections, forming in each of the rectangular sections avertical row of rectangular holes in order to allow the free passage ofairthrou-gh the spaces inclosed in the sections 4, 4. The holes 13 areof uniform size and are uniformly spaced in each of the vertical frontand rear sides of the rectangular sections so that, when the sectionsare assembled to form the radiating section, the front and rear sides ofthe apparatus will present a latticed appearance. with the rectangularopenings 13 arranged in parallel horizontal and parallel vertical rows.

When the several r'ectangular sections are assembled and the pans 10inserted in their upper and lower ends the upper and lower ends and alsothe front and rear edges of the sections are dipped in melted solder,

causing the contacting surfaces between the sections and also betweenthe sections and pans 10 to be securely attached and their joints closedto the admission of water. The radiating section 3, constructedsubstantially as described aboveand with its joints securely solderedtogether, is then placed between the upper and lower water chambers 1and 2 and the three sections of the apparatus soldered together. Aswater is forced into the upper chamberl, it passes in smallstreamsthrough the restricted semi-circular channels 9 into the lowerchamber 2 from which it is passed around the cylinders of an explosionengine and returned to the upper water chamber 1. Air passes in thedirection shown by the arrows, a, a, Fig. 1, through the interior of therectangular sections, entering through the rectangular spaces upon thefront side of the radiating section 3 and, passing in contact with thewalls of the water channels 9, finds its exit through the rectangularopenings at the rear of the radiating section, a current of air beingmaintainedin the direction of the arrows a, a, by the forward movementof the vehicle, aided in the usual manner in motor vehicles by means ofa fan placed immediately behind the radiating section.

While the semi-circular form of the water channels 9 we considerpreferable, as they are more easily formed and afford greater resistanceto outside pressure, we do not confine ourselves to this form. Ifpreferred, a single narrow space can be formed between the strips ofmetal 5 and 6, as shown at 15, Fig. 4:, and the sheet metal strips bentto form the sides 16, 16, of adjacent sections.

We claim,
